Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete testing technology, specifically to a concrete permeability testing device. Background Technology
[0002] Permeable concrete refers to concrete with a porosity of 15-25%, also known as no-fines concrete. It is made by mixing cement, coarse aggregate and water in a certain proportion.
[0003] Before using permeable concrete, it is necessary to test the permeability of the permeable concrete test blocks to ensure the permeability quality of the permeable concrete. Existing testing equipment cannot fix the concrete test blocks, so some liquid falls directly into the measuring cylinder without passing through the concrete test blocks during the test, resulting in a large error in the permeability calculation results. Therefore, we propose a concrete permeability testing device. Utility Model Content

[0006] An adjustment component, located on one side of the top of the base, is used to adjust the height of the fixed frame;
[0007] A fixing component, located at the top of the fixing plate, is used to fix the concrete specimen.
[0008] The fixing component includes a horizontal plate located on both sides of the top of the fixing plate. Narrow cylinders are symmetrically arranged on one side of the horizontal plate, and springs are arranged inside the narrow cylinders.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] The concrete permeability testing equipment uses a clamping plate to fix the concrete specimen, preventing it from shifting during testing and wasting liquid during descent, which would increase the error in permeability measurement. The fixing frame wraps around the clamping plate during descent, ensuring full contact between the liquid and the concrete specimen. Furthermore, the combined action of the long and short pads lifts the measuring cylinder, bringing it into contact with the groove at the bottom of the fixing plate, preventing liquid waste during testing. The liquid in the measuring cylinder can also be reused after testing. This equipment reduces errors in concrete permeability calculation. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.
[0024] like Figures 1-4 As shown, this utility model provides a technical solution: a concrete permeability testing device, including a base 1, which provides support for the main body of the device; an adjustment component 2, which is set on one side of the top of the base 1, for adjusting the height of the fixing frame 209 so that the fixing frame 209 fits over the outside of the concrete specimen, facilitating direct contact between the liquid and the concrete specimen; and a fixing component 3, which is set on the top of the fixing plate 101, for fixing the concrete specimen to prevent the concrete specimen from shifting during concrete permeability testing, which could lead to liquid leakage and increase the error in concrete permeability testing.
[0025] like Figure 1-4As shown in the embodiment of this application, the fixing component 3 includes a horizontal plate 301, which is located on both sides of the top of the fixing plate 101. A narrow cylinder 303 is symmetrically arranged on one side of the horizontal plate 301. A spring 304 is arranged inside the narrow cylinder 303. A wide cylinder 302 is arranged on the outer wall of the narrow cylinder 303. A clamping plate 305 is arranged on one side of the wide cylinder 302. A concrete specimen is arranged between the clamping plates 305. Specifically, the concrete specimen can be fixed under the action of the clamping plates 305. The concrete specimen to be tested is taken out and placed on the clamping plates. Between 305, during the placement of the concrete test block, the clamping plate 305 translates. During the translation of the clamping plate 305, the wide cylinder 302 slides along the outer wall of the narrow cylinder 303. During the sliding of the wide cylinder 302, the spring 304 is compressed, and the spring 304 generates a deformation force. The deformation force generated by the springs 304 on both sides of the concrete test block is the same. The deformation force of the springs 304 acts on the clamping plate 305 to fix the concrete test block, thereby preventing the concrete test block from shifting during the permeability test and affecting the final permeability result.
[0026] like Figure 1-4 As shown in the embodiment of this application, a long pad 102 is provided at the top of the base 1, short pads 104 are provided on both sides of the long pad 102, a measuring cylinder 103 is provided at the top of the short pads 104, and a fixing plate 101 is provided above the measuring cylinder 103. Specifically, the fixing plate 101 provides an installation environment for the fixing component 3. The fixing plate 101 is provided with a completely penetrating central groove, the size of which is the same as the size of the concrete test block, so that the liquid can fall directly from the concrete test block into the measuring cylinder 103 without leaving any residue on the fixing plate 101. The measuring cylinder 103 is used to collect the liquid that passes through the concrete test block. The measuring cylinder 103 is initially set at the top of the base 1. Before testing, the long pad 102 and short pads 104 are placed in, which can raise the height of the measuring cylinder 103 so that the top of the measuring cylinder 103 abuts against the fixing plate 101. The circular groove at the bottom of the fixed plate 101 is larger than the concrete test block and is the same size as the measuring cylinder 103. A cross groove is provided at the top of the base 1 to accommodate the long pad 102 and the short pad 104 and to guide and limit their movement. First, the measuring cylinder 103 is placed at the top of the base 1. Then, the measuring cylinder 103 is manually lifted. The long pad 102 is inserted into the cross groove. After one end of the long pad 102 rests against the vertical plate 201, the short pads 104 are inserted on both sides of the long pad 102. A through groove is provided in the center of the long pad 102 to limit the insertion of the short pads 104. Then, the long pad 102 and the short pad 104 work together to support the measuring cylinder 103 and lift it up so that when the liquid passes through the concrete test block into the measuring cylinder 103, no liquid will splash to the outside.
[0027] like Figure 1-4As shown in the embodiment of this application, the adjustment component 2 includes a vertical plate 201, which is located on one side of the top of the base 1. A top plate 212 is provided on one side of the top of the vertical plate 201. A motor is provided at the middle of the top of the top of the top plate 212. A threaded rod 203 is connected to the output end of the motor. A threaded seat 202 is provided on the outer wall of the threaded rod 203. A slide rod 205 is provided on the inner side of the threaded seat 202. A fixing block 204 is provided on one side of the threaded seat 202. The fixing block 204 is located in the lifting groove 207. A support plate 210 is provided on one side of the fixing block 204. A plurality of sliders 206 are provided on one side of the support plate 210. The sliders 206 slide in the sliding groove 208. Specifically, the motor is used to provide power for the lifting of the fixed frame 209. The motors in this application are all connected to an external power supply and are connected to the power supply. Controlled by the control system, the motor drives the threaded rod 203 to rotate. The threaded rod 203 is threadedly connected to the threaded seat 202. While the threaded rod 203 rotates, it can drive the threaded seat 202 to rise and fall. The slide rod 205 is used to guide and limit the threaded seat 202. While the threaded seat 202 moves, it drives the support plate 210 to rise and fall through the fixed block 204. The fixed block 204 slides in the lifting groove 207 to limit the movement distance of the threaded seat 202. During the movement of the support plate 210, the slider 206 is driven to slide in the sliding groove 208. The slider 206 is used to guide the support plate 210, and the sliding groove 208 is used to limit the movement distance of the support plate 210. While the support plate 210 moves, it drives the fixed frame 209 to translate.
[0028] like Figure 1-4 As shown in the embodiment of this application, a fixing frame 209 is provided on the other side of the support plate 210, and a sealing strip 211 is provided on the inner side of the bottom end of the fixing frame 209. Specifically, the fixing frame 209 can wrap the concrete test block. During the descent of the fixing frame 209, the arc-shaped grooves on both sides of the fixing frame 209 gradually come into contact with the wide cylinder 302. After the fixing frame 209 contacts the outer wall of the wide cylinder 302, the sealing strip 211 on the fixing frame 209 will contact the clamping plate 305 and form a sealed connection. The inner wall of the fixed frame 209 located above the sealing strip 211 is the same size as the concrete specimen, which allows the liquid to fully contact the concrete specimen during testing. When calculating the permeability of the concrete specimen, the cross-sectional area of the water pipe, the thickness of the concrete specimen, the permeable area of the concrete specimen, the permeability time of the concrete specimen, and the head difference between the bottom of the measuring cylinder 103 and the bottom of the concrete specimen from the start to the end of the test are measured. After obtaining the corresponding data, the permeability of the concrete specimen can be calculated according to the corresponding calculation formula.
